IMPROVEMENT IN SIPHONS.

Specication forming part of Letters Patent N o. 201,134, dated March 12,1878; application filed I January 23, 1878.

siphon which will be simple in construction,

and which will be automatically opened and closed by means of a valvepivoted to alange attached to the longer arm, and provided with a iioat,all arranged and adapted for the purposes hereinafter set forth.

In the drawings, Figure l is a side elevation of a siphon constructedaccording to my invention. Fig. 2 is a side view of the iloat and valve,with the latter closed on the mouth of the inlet-arm; and Fig. 3 showsthe oat elevated and the valve opened.

a is the siphon-tube, bent'in ordinary form, so as to provide the shortarm a and the longer arm a2, as shown. Near to the open end of theshorter arm al I attach a suitable flange or support, b, which extendsoutward a sufficient distance to afford facilities for attaching thevalve c. The end b1 of the siphon-tube projects below this ange, asshown. The

valve c is provided with an arm, c1, which is pivoted to a lug, c2,affixed on the under side of the iiange b. The lug c2 is made longenough so that when the valve cis on the end of the siphon the arm c1will rest in a horizontal position, as shown in Fig. 2. The arm c1 ispivoted eccentrically, so that the valve c, which is placed on theshorter end, will be held against the end of the tube by the greaterweight of the longer end, except as otherwise hereinafter explained. Onthe longer end may be attached a weight, d, if desired, in order to makeit act with greater promptness. e is a float or buoy, made of cork orother light material, and attached by a stem or support, el, to theouter end; and on the upper side of the longer part of the arm c it isso attached that when the arm cl is in a horizontal position, as shownin Fig. 2, it will be above the plane of the mouth of the arm al ofv thesiphon a. f is a reservoir, and is designed to hold water, in which theoutlet end of the siphon may be kept constantly immersed, as shown; andit has an outlet, f', from which the water Hows when the siphon is inoperation.

The operation of this device will be readily understood. The siphon isfilled by any ordinary means, and the open end of the shorter arm placedin the water that is to be drawn off. The water, acting on the iloat e,will raise it and lift the valve o off the end of the pipe, as shown inFig. 3. When the water has been lowered near to the end of the pipe thefloat will fall with the water till the valve will rest firmly againstand close the tube, as shown in Fig. 2, and stop the ow. When the waterin the tank rises so as to lift the float the valve will be opened, andthe liow of water through the siphonwill' immediately commence.

I am aware of the existence of the patent to A. M. Ramey, January 21,1877, and I do not claim the invention set forth in his specification;but

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

In combination with the siphon a, the rocking bar cl, pivotedintermediately between its ends to the lug c2, and having on one end thevalve c and on its opposite end the oat e, supported on the stem or armc1 'above the plane of the mouth of the inlet-arm al of said siphon,substantially as and for the purposes set fort-h.

In testimony that I claim the foregoing as my own I affix mysignature'in presence of two witnesses.
